Female and Male Marijuana Plants
Marijuana plants are either male or female. The male Marijuana plants produce pollen which pollinates the flowers of the female Marijuana plant, which once pollenized, produce seeds. If the female Marijuana plant isn't pollenized (if there are no male Marijuana plants nearby producing pollen), the flower/buds continue to develop and produce THC. Female Marijuana plants which are not pollenized are referred to as sinsemilla (without seeds). Usually 30-50% of the Marijuana plants are male.

Cannabis in temperate climates begin to show his sexual identity by the end of July (end of January in the southern hemisphere) in different dates according to the varieties, Marijuana being the resinous flower of female cannabis plants intended for seed production, in absence of pollen buds turns out pure sensimilla weed and is gentle and sweet to smoke.

Males are often, but not always, tall with stout stems, sporadic branching and few leaves. Males are usually harvested except those used for breeding, after their sex has been determined, but before the pollen is shed. When harvesting, especially if close to females, cut the Marijuana plant off at the base, taking care to shake the male as little as possible. This helps prevent any accidental pollination by an open male flower.

It is very important to get rid of male plants on time, as they are unwanted pollen carriers. By the early flowering stage male cannabis, if compared to female's, shows quite a different structure but the characteristic excrescencies would be the sex indicator this are called primordia and will emerge by the side of the third or fourth internodes in the main stem.

Female cannabis are completely revealed when the characteristic "V" shaped pistils become visible, all this to a close observation. Outdoors males will uncover themselvesapproximately three weeks before the females, indoors sexing of both males and females happens within a week to ten days according to the variety.

Most commonly, a flowering female Marijuana plant will develop staminate flowers, though the reverse is also true. Primarily male hermaphrodites are not as well recognized only because few growers let their males reach a point of flowering where the pistillate would be expressed

That kind of research could be a lot of fun

so I thought it worth mentioning that the environment influences the sex of the seeds too.

"

Humidity. Now this is the tricky one. High humidity levels only promote fungi and mold development and lowering humidity levels is the way to cure most of this rot but by keeping those humidity levels up in or around the 70 rH factor will help to produce more females. If you have a low humidity grow room then you should get to hold of a humidifier. Now high humidity levels like 70rH cause the medium to dry out a lot quicker so you got to keep this under control too. Keep those mediums moist and those rH levesl at 70. This will help to improve those female to male ratios. Again, getting them on the up and up.

If you run the 24/0 photoperiod then do not allow those temps to go anywhere above 85F unless you have an equatorial strain. 75F is the best but going a little lower is not a problem for helping those female ratios. If you can get in at around 65F then those females are going to be popping up all over the place. The problem with this is that some growers like to use the 18/6 photoperiod and when the lights are off the temps drop from around 65F to 50F and even less. Try not to be below 55F because this has the adverse effect on the plants producing more males than females. Again between 65F and 75F is where you want to be during the 3rd to 4th week of vegetative growth, the preference being 70F."
